Question

A MARBLE TILE MEASURE 25 CM BY 20 CM . HOW MANY TILES WILL BE REQUIRED TO COVER A WALL OF SIZE 4M BY 3M

Answer 1

Answer:

Step-by-step explanation:

using formula ( length into breadth ) Area of rectangle

then

25cm multiply 20cm we get 500cm^2

and

400cmm multiply 300cm we get 120000cm^2

because 1m = 100 cm

then divide 120000cm^2 by 500cm^2

we get 240 tiles

Answer 2

If 1m=100 cm
4m=400cm and 3m=300cm
400 multiply 300=120000

25x20 (as per question)
500cm

120000 divide by 500
It requires 240 tiles
